Julia is asked to bake macarons for the magazine's unveiling of 'The Best Garden in Peridale' party, but with death striking the village, she has more important things to worry about.

With her old friend and newspaper reporter, Johnny, by her side, Julia must uncover the truth before every member of the club is crushed like an unwanted weed.
